Summary: This week we learned more about sound, how we hear it, and how it travels. Some ways that sound helps us is by allowing us to see babies in their mother's stomachs. It can also allow us to take pictures of the unborn baby, this is called ultrasound. I also learned that when sound enters our ears it’s carried to a nerve in the brain that allows us to recognize a sound. Another thing I learned is that when sound is reflected off of a surface it’s called a reflection, or an echo. Sound also allows multiple animals like a bat or whales to use echo location which helps them find food and their family if they get separated.
SP2: Developing and using models
Models make it possible to go beyond things you observe and simulate a world not yet seen. Models enable predictions of the form “if…then… therefore” to be made in order to test hypothetical explanations.
Did you build a model, draw a picture, created a concept map, etc?
Yes this week we needed to sketch a picture of an instrument that we were going to build. Along the way we’ll make changes to our models.
